Specification of Letters Patent.

f Application led October 80, 1915.` Serial INo. 58,840.

To all whom t may concern.'

Be it known-that I, ADAM E. FENDRICH,

j' a citizen of the United States, residing at lVeehawken, in the countyof Hudson and State of New Jersey, have invented cerv tain new anduseful Improvements in Tooth- Brushes; and I do hereby declare thefollowing to be a full, clear, and exact` description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same. y The invention relates to improvements in toothbrushes.

The object of the present invention is to improve lthe construction oftooth brushes and to provide a simple, practical and comparativelyinexpensive tooth brush adapted to brush the teeth with an up and downmotion of the bristles of the brush and capable of also protecting thegums and of preventing the same from being injured by the solidy portionof the brush head.

A further object of the invention is to provide a sanitary tooth brushlof this chaiacter capable of easy operation from the end of the handleto produce a partial rotary `movement of the bristles alternately inopposite directions.

With these and other objects in View the invention consists in theconstruction and novel combination and arrangement of parts hereinafterfully described, illustrated'in thev accompanying drawings and pointedout in the claim heretoappended, it being understood that variouschangesin the form, proportion and minor-'details of construction may beresorted. to without departing from the spirit or sacrificing any of theadvantages of the invention.

In the drawing Figure 1 is a planview of atoothbrush constructed inaccordance with thisinvention, I

Fig. 2 is a longitudinal sectional view of` the same,

Fig.v 3 is a transverse sectional View on the-line 3-3 of 2,

Fig. 4 is a similar view on the line 4 1 of Fig. 2.

Like numerals of reference designate corresponding parts' in the severalfigures of the drawing.

In the accompanying drawing in which is illustrated the preferredembodiment of the invention, 1 designates a brush member consisting of abar of any suitable 4material circularjin cross section to rotate withina hollow handle 2 and provided at its outer portlon with bristles 3extending over approximately one-half the surface of the outer portionorhead 4. The handle 2 is of tubular form and is provided with a shank orstem 5 connecting the handle with anouter substantially semi-cylindricalshell 6 :adapted to form a ard. The substantially semicylindrical s ellhas an end wall '7 which" may be secured to the shell after the partshave beenka'ss'embled or the shell may be constructed in' any otherdesired manner to enable the parts to be assembled.

. The outer end of the brush member 1 is provided with a recess 8forming spaced Patented. May 2e, 1917.

shoulders 9 which are adapted to engage a I lug or projection 10 forlimiting the rotary movement of the brush member. The shell4 or casing 6is designed to be provided with one or more perforations or apertures 11for draining and Ventilating the tooth brush.

.The brush member 1 is preferablv reduced at its inner end to form aneck u12 which passes 4through an opening 13 in the end wall or portion14 of the tubular handle 2 and has secured to it an operating handle ordisk 15 by means of Twhich .the brush member is partially rotated tocause the bristles of the toothbrush -to brush the teeth with an up anddown motion. The operating device may be secured to the reduced terminalportion-or neck 12 in any desired manner and it will be clear that thetooth brush may be easily held in the hand with the bristles in positionfor engaging the teeth and that the handle member may be readilyvoperated to cause the bristles to thoroughly brush the teeth and engagethe same at thesidesthereof as well as the facesv 'of the' teeth.

In practice, the toothbrush will be provided with a suitable cover whichmay be constructed in any desired mannerand the handle may beconstructed in one or more pieces.

It will be seen that the tooth brush is exceedingly simple inconstruction and that the shell or casing in which the brush head isrotatively mounted forms a guard and that only the bristles arepermitted to come in contact with the teeth.

What is claimed is A tooth brush including a tubular-handle providedwith a shell or casing of substantially semi-cylindrical form, a rodcircular in crossY section and. mounted for rotary by said shoulders forlimiting the rotary lmovement; in the tubular handle, said rod ormovement of the rod. 10 bar extending into the shell or casing, bris- Intestimony whereof I aiiX my signature tles covering a portion of thesurface of the in npresence of two Witnesses. rod extending into saidshell, said rod being ADAM E.
